TYPE-C interface PD USB HUB fast charging docking solution
Nowadays, the type-c interface can be seen everywhere, whether it is mobile phones, laptops, tablets, smart home appliances, audio, headphones, etc., it can be said that it has penetrated into all aspects of life. Let’s talk about the origin of the type-c interface: The USB-IF organization launched the USB Type-C port (also known as USB-C port) in 2015, which was an epoch-making change, also known as the first year of Type-C. . Later USB 3.1, USB 3.2 and USB4 were gradually introduced
After 20 years, from USB-A to USB-B to USB-C today, the era of unifying various device interfaces is finally coming. As a new interface, type-c supports positive and negative plugging and has more pins (24), and has now become the mainstream. Then some devices only have a type-c interface. For example, a laptop with a type-c interface wants to connect to a speaker, a mouse, a keyboard, etc., and the interface is not enough. At this time, a docking station with a type-c interface is needed. solve this problem.
Dock, also known as docking station, is popular because of the limited number of USB or video interfaces in notebook computers, and users want to expand more or more types of interfaces to meet diverse application needs.
There are many application scenarios for the type-c hub docking station. It can not only connect to laptops and mobile phones, but also can be used to connect to Switch game consoles and tablets as screen projection. In addition, the type-c hub expansion dock has a C port charging port, which can quickly charge the device with a maximum of 20V3A (60W) PD, so that the screen is charged at the same time, and the screen will not run out of power.
The type-c hub expansion dock PD fast charging uses the LDR6282 chip. The dual DRP and USB PD3.0 functions of the LDR6282 enable those expansion docks with dual C ports to have two C ports that can be blindly plugged at will. , and supports the Nintendo Switch video game extension. Users do not have to distinguish which one is a charging port and which one is a smart device. LDR6282 will analyze according to the USB PD protocol and automatically assign the connection relationship between the two C ports. Just like the smart adaptation of the Macbook Pro to multiple C ports.
The dual-port DRP USB PD Controller LDR6282 has successfully passed the USB-IF PD3.0 certification, TID: 2127. The LDR6282 chip has dual C-port DRP and USB PD3.0 control functions, and is widely used in USB-C Docking, USB-C monitors, USB-C mobile phone audio adapters, embedded Android/linux systems and other occasions. On the basis of the PD3.0/QC2.0/QC3.0 protocol, it is specially adapted for the video extension function of the Nintendo game console Switch, and the compatibility is very good.
The chip also has a built-in 64K flash that can upgrade the internal firmware through a cloud connection. So that the complex product design can also rest in peace, even if the product has been delivered to the end consumer, the firmware can still be upgraded through the mobile phone APP or the PC application.
